Semiconductor Synthesis and Application for the Treatment of Ciprofloxacin Antibiotic by Solar Heterogeneous Phocatalysis
The objective of this study is to examine the relevance of treatment with the antibiotic ciprofloxacin by heterogeneous solar photocatalysis. The efficiency of the catalyst (ZnO) synthesized by the precipitation method is also determined. The solid- visible UV analysis showed that the spectrum reveals an absorption peak at 364 nm, which can be attributed to the band gap with of ZnO, in the case of the electron transition from the band of valence towards the conduction band (2p 3d) [3] and [4]. Under optimal conditions, initial ciprofloxacin concentration 10 ppm, ZnO dose 0.1 g/L and free pH (6) ; treatment by solar photocatalysis in the presence of ZnO showed a ciprofloxacin elimination yield of 87% is obtained after 240 min of treatment. The total degradation of ciprofloxacin is observed, by the disappearance of the ciprofloxacin absorption peak during the treatment time. Analysis by infrared spectroscopy showed that only two groups are obtained O-H and C=O at 3500 cm-1 and 1600 cm-1, respectively after 240 min of oxidation. The BOD5/COD ratio increased from 0.005 initially to 2.13 after 240 min of ciprofloxacin treatment by solar photocatalysis. The relevance of the solar photocatalytic process is shown. At the end of these results, the relevance of the treatment of ciprofloxacin antibiotic by solar photocatalysis in the presence of the semiconductor ZnO is shown.
